ABSTRACT
Anatomy was not an independent science, but every medical book began with a description of the human body and its functions. Studying anatomy was essential for every student, [of medicine] because it was questioned in every examination. Arab and Islamic physicians learnt that the Greek anatomy was deficient and not complete; they began to discover mistakes and failures which they corrected, and added information as well as new discoveries. I studied three medical books, Urndat al-islah fi sinaat al-jarrah short AI-Umdah by lbn al Quff from the 13th century. lbn al nafis-arab Galen, 13th century. Al kulliat, by lbn Rushd [averros] 11th century. 1- Islam doesn't prohibit body dissection. 2-Moslem physicians have practiced some dissection. 3- there has been new discoveries that were impor tant to the development of medicine in the following period. 4- the standard of anatomy science was equal to the general standard of science at that time
